ANCHORl OR SUPPORTING PLATE.

SPECIFICATION forming part of Letters Patent No. 526,411, dated September 25,1894. Application liled July 5,1894- Serial No. 516,611- (No model.)

To a/ZZ whom it may concern,.-

Beit known that I, JOHN PIRKL, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,have

l invented certain new and useful Improvements in Anchor or Supporting Plates; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings,

making a part of this specificatiomand to the letters of reference marked thereon.

The present invention has for its object to provide a simple and eective anchor or supporting plate for the ends of beams or girders whereby the same will possess the required porting plate constructed substantially as shown in the drawings and hereinafter described and claimed.

`ends of horizontal beams or girders D.

rlhe plate C may be of any suitable size or shape to conform to the size and shape of the post-sections and beams or girders with which the plates are to be used.

The plate C has flanges a which project from the upper and lower sides of the plate and eX- tend the entire length thereof so as to hold in place the ends of the post-sections A B and also the ends of the beams or girders D. It is not essential that the flanges a should extend upon the under side of the plate the entire length thereof butonly a suicient distance to hold the end of thelower post-section in position by the aid of the transverse ribs b upon the upper and under side of the plate. The anges a. and the transverse ribs b not only hold the ends of the post-sections against displacement but materially strengthen the.

plate and form a perfect support for the ends of the beam or girder. t

Upon the upper side of the plate C at each end thereof are lugs E of wedge-shape or in other words having an inclined upper surface c and a vertical end cl. This peculiar shape of the lugs enables the mortise to be made in the beam or girder with two cuts of the chisel in which the lug is to engage besides enabling the beam or girder to easily release itself when burned through in case of re and without injury to the anchor or supporting plate or forcing it out of position.

Having now fully described my invention, what I claim as new, and desire to secure by A JOHN PIEKL.
